SCUTTLE OR SKYLIGHT OPERATOR.

SPECIFICATION forming part of Letters Patent No. 606,057, dated June21., 1898.

Application filed February 12, 1898, Serial No. 670,065. (No model.)

To ctZZ whom, it may concern:

Be it known that I, FERDINAND HAYES, a citizen of the United States,residing at New York, (borough of Brooklyn,') in the State of New York,have invented an Improvement in Scuttle or Skylight Operators, of whichthe following is a specification.

Scuttles upon buildings, especially dwellings, are frequently fitted sothat they can be raised and propped up for ventilation; but it isgenerally inconvenient to climb a ladder and prop up the scuttle, and inaddition to this the scuttle is liable to be blown over by the wind orbe raised sufiiciently from outside for a person to pass into the house.

The object of the present invention is to raise the scuttle or skylightfrom the fioor below, to hold the same in an elevated position, and toprevent the scuttle being raised from the roof either by the wind or byany person seeking to enter the building through the scuttle.

In carrying out this invention I make use of a lever with a segmentalsheave, to which is connected one end of a rope or chain that passesover a pulley, so that by drawing upon such rope or chain the scuttlecan be elevated more or less by the action of the lever, and atriangular support is employed for the pivot of the lever and for a stopthat arrests the movement of the lever, and these parts are made so thatthey can be applied at either side of the scuttle-coaming, and a cord orchain connected on the under side of the scuttle passes down to aclamp,.by which the scuttle can be kept or held down at any point towhich it may be raised.

In the drawings, Figure 1 is a section through the scuttle and coaming,and Fig. 2 is a cross-section near the line 2 2.

A portion of the roof is illustrated atA and the coaming or scuttle-wayat B, and Oillustrates a scuttle hinged at 4, so as to be raised orlowered, and the chain D is usually provided to prevent the scuttlepassing beyond a vertical position. These parts are simply illustrativeof a scuttle or skylight of any desired character.

The lever Eis made with asheave-segment 5, and a pivot 6 at the junctionof the sheavesegment and lover is advantageously made by a screw passinginto the coaming or senttle-way, and this is supported by the frame F,which is advantageously triangular and connected by screws 7, passingthrough washers or blocks 8, and this frame F is preferably made similaron its two surfaces, so that the frame and lever can be applied ateither side of the coaming or scuttle-Way, and the'screw stop 9 passesthrough the frame and serves to arrest the movement of the lever andsheave-segment in opening the scuttle, such sheave-segment coming incontact with the screw-stop at the notch 10.

The shoe-piece G is connected at 11 to the upper end of the lever E, andthis shoe-piece slides against a slat or strip II, that is connected tothe under side of the scuttle O and occupies the position shown bydotted lines in Fig. 1 when the scuttle is closed and slides into theposition shown by full lines as the scuttle is opened.

I find it advantageous to employ the sliding shoe upon the slat orstrip, as there is sufficient friction between the parts to lessen therisk of the scuttle closing too rapidly when being lowered, ashereinafter described.

The cord or chain I is fastened at one end to the sheave-segment,preferably by being passed through a hole, and such cord or chain is inthe groove of the sheave-segment and passes over a pulley K and descendsaround the pulley L and passes up and is connected at the upper end tothe scuttle, advantageously by a loop passing over the hook 12 upon theunder side of the scuttle, and this cord or chain I passes through theclamp M, preferably formed of two side pieces and a pivoted lever havingan eccentric and clamping end, as seen in Fig. 2, for pressing upon andholding the cord or chain when the lever is. turned in either onedirection or the other;

but such cord or chain can pass through the clamp freely when the handleor lever of the clamp is horizontal.

The cord or chain I can be taken hold of by hand, or a branch cord andhandle I can be made use of for drawing down the cord, and swinging thelever and sheave-segment from the position shown by dotted lines inopening the scuttle or skylight to any desired extent, and by clampingthe cord or chain'at M the scuttle is held so that it cannot be raised,and by properly proportioning the parts, as illusthe cord or chainbetween the clamp and the hook.

When it is necessary to open the scuttle, the cord or chain is to beseparated from the hook 12, and the scuttle can be opened in theordinary manner.

I claim as my invention' 1. The scuttle or skylight opener composed of alever and sheavesegment, a frame and pivot for supporting the lever andsheavesegment, and a cord or chain passing from the sheavesegment andover a pulley by which the parts are moved and the scuttle raised, theend of the lever acting upon such scuttle, substantially as set forth.

2. The combination in a scuttle or skylight opener, of a triangularframe adapted to bein g connected at either side of the scuttle-way orcoaming, a lever and sheave-segment, a pivot for the same passingthrough the triangular frame, a stop upon the frame for limiting themovement of the lever, a cord or chain connected at one end to thesheave-segment, and a pulley over which such cord or chain passes forraising the scuttle, substantially as set forth.

3. ihe combination in a scuttle or skylight opener, of a triangularframe adapted to being connected at either side of the scuttle-Way orcoaming, a lever and sheave-segment, a pivot for the same passingthrough the triangular frame, a stop upon the frame for limiting themovement of the lever, a cord or chain connected at one end to thesheave-segment, a pulley over which such cord or chain passes forraising the scuttle, a connection upon the scuttle for the other end ofthe cord or chain, and a clamp for holding the same, substantially asset forth.

Signed by me this 11th day of February, 1898.
